Parthenocissus inserta inflorescence A. A. Reznicek inflorescence

Roadsides, fencerows, stream banks, and thickets; also rock outcrops, talus slopes, and rocky forests and savannas; open forests both swampy and upland.

In our specimens, the undersides of the leaves and especially the petioles are usually completely glabrous, although occasionally puberulent. The berries average a little larger than in P. quinquefolia and are often 4-seeded. This species is sometimes called P. vitacea (Knerr) Hitchc.; see Pringle (2011) for the nomenclature.

Parthenocissus inserta scrambles over shrubs, fences, open banks, rock ledges, etc. and fruit is formed low enough to be commonly seen; P. quinquefolia is high climbing and fruits are not commonly seen, presumably forming mostly high in the canopy.
